Nicole Richie and Joel Madden Tie the KnotThe father of the bride, Lionel Richie, hosted the wedding at his 28-room Los Angeles estate as Nicole Richie, 29, married musician Joel Madden, 31, after four years and two kids together.

Guests included Gwen Stefani, Ashlee Simpson, Kris Jenner and the groom's twin brother, Benji Madden (Joel's Good Charlotte bandmate), and was officiated by Rev. Run, who, in addition to his rapping career, practices as an ordained Pentecostal minister . A guest a the wedding told Us Magazine of the couple's choice of clergy, "They both appreciate his family values and he is an inspiration for both. They both also respect his faith, too."

In addition to the celebrities in attendance, the couple invited one very unexpected guest: Before the ceremony, People.com reports, a trained elephant was seen being led onto the grounds -- where large white tents had been set up amid the estate's gardens. There's been no word yet on how exactly the pachyderm participated in the nuptials.
